The present invention relates to a roll roughness measuring apparatus, and more particularly, to a portable roll roughness measuring apparatus, which is portable so that roll roughness measurement can be made simply and quickly.

In general, since the surface condition of the roll (Roll) widely used in steel mills has a great influence on the surface quality of the produced product, the surface condition of the roll is periodically measured using a tactile roughness measuring device.

The roughness measuring device is for measuring the surface roughness of the object, and measures the cross-sectional curve that appears when the surface of the object is cut at right angles to the average surface. In addition, a tactile roughness measuring device, which is a precision measuring device that calculates roughness by moving a sharp tactile hand made of diamond in contact with a material surface and amplifying minute fluctuations of the tactile hand with an electrical signal, is widely used.

1 is a configuration diagram showing the roll roughness measuring apparatus according to the prior art as a whole, a trolley 110 configured to be movable by receiving power from the driving motor 112 and mounted on the upper portion of the trolley 110 to rotate. One or more rotary rolls 114 that are driven in the axial direction by receiving power from the drive motor 116 and installed on the support 120 fixed to the floor of the facility are provided with power from the drive motor 122 to receive the power. It includes a roughness gauge 130 that is moved in the direction.

That is, in order to measure the roughness of the roll, the roll R disassembled in various facilities is placed on the upper part of the rotary roll 114 of the trolley 110, and then the trolley 110 is moved to determine the roughness of the roll R. Position it so as to be at the lower portion of the 130, and then lower the touch rod of the roughness gauge 130 so as to contact the outer surface of the roll R, and then drive the rotary roll 114 to rotate the roughness of the roll R. To measure. In addition, by repeating the above operation while moving the trolley 110, roughness is measured at a number of places in the longitudinal direction of the roll (R).

Such a conventional roll roughness measuring method has a problem that excessive work time is required because it requires a very cumbersome work process such as disassembling the roll in a facility and measuring roughness while moving a bogie in order to measure roughness.

Of course, in order to measure the roughness of the rolls more quickly, a skilled worker having many experiences removes the roughness gauge 130 from the support 120 and directly measures the surface roughness of the roll R, Roll roughness lacks objectivity and has a problem that evaluation of the surface state of the roll R cannot be accurately made.

An object of the present invention is to provide a portable roll roughness measuring apparatus which is configured to be movable to measure the roughness quickly and accurately without disassembling the roll in a facility.
